Fire grate type incineration apparatus

Abstract

The present disclosure relates to a fire grate type incineration apparatus, which includes movable fire grates and fixed fire grates alternatively arranged in a step pattern and incinerates waste while moving the waste to a discharge hole by the operation of the movable fire grates, wherein a channel is formed in the fixed fire grates so that a coolant cools the fixed fire grates while flowing along the channel, wherein the air introduced into the movable fire grates cools the movable fire grates and then is preheated and supplied into the incineration apparatus through an exhaust hole formed in the movable fire grates.

What is claimed is: 
     
         1 . A fire grate type incineration apparatus, which includes movable fire grates and fixed fire grates alternately arranged in a step pattern and incinerates waste input thereto while moving the waste toward a discharge hole by the operation of the movable fire grates,
 wherein a channel is formed in the fixed fire grates so that a coolant cools the fixed fire grates while flowing along the channel, and air introduced into the movable fire grates is supplied into the incineration apparatus after cooling the fire grates through an exhaust hole formed in the movable fire grates, and   wherein the movable fire grates or the fixed fire grates located to connect each other in the lateral direction of the same level have steps at sides thereof so as to be engaged with another movable fire grate or fixed fire grate at the sides thereof.   
     
     
         2 . The fire grate type incineration apparatus according to  claim 1 , wherein a channel tube is formed in the front end of the fixed fire grate toward the inside of the fire grate type incineration apparatus to which waste is continuously input, and the channel tube is surrounded by a shield plate. 
     
     
         3 . The fire grate type incineration apparatus according to  claim 2 , wherein an inlet tube and an outlet tube are formed at the rear end of the fixed fire grate, and the inlet tube and the outlet tube are connected to the channel tube. 
     
     
         4 . The fire grate type incineration apparatus according to  claim 1 , wherein a shield plate is formed at the upper surface of the fixed fire grate. 
     
     
         5 . The fire grate type incineration apparatus according to  claim 2 , wherein a shield plate is formed at the upper surface of the fixed fire grate. 
     
     
         6 . The fire grate type incineration apparatus according to  claim 3 , wherein a shield plate is formed at the upper surface of the fixed fire grate. 
     
     
         7 . The fire grate type incineration apparatus according to  claim 1 , wherein an exhaust hole is formed at the front end of the movable fire grate toward the inside of the fire grate type incineration apparatus to which waste is continuously input, and air introduced into the movable fire grate is preheated and supplied into the fire grate type incineration apparatus through the exhaust hole. 
     
     
         8 . The fire grate type incineration apparatus according to  claim 4 , wherein the shield plate is made of chrome steel or ceramic material. 
     
     
         9 . The fire grate type incineration apparatus according to  claim 5 , wherein the shield plate is made of chrome steel or ceramic material. 
     
     
         10 . The fire grate type incineration apparatus according to  claim 6 , wherein the shield plate is made of chrome steel or ceramic material.
